SPECIFICATION forming part of Letters BatentNo. 381,153, dated Apri1 17, 188d. I

Application filed 'June 17, 1887.

To all whom it may concern.-

Be it known that l, EDWARD GEORGE MAR- TIN, a citizen of the United States, residing at- Concordia, in the county of Cloud and State of vapor-burner which is adapted to heat water and to generate steam at the same time that the flame is used for ordinary cookingpurposes, thus enabling the vapor-stove to be supplied with steam and hot water without any greater zontal sectional view taken on the line :0 a; of o expense than that incidental to maintain the flame ordinarily used, andthereby effecting a, great economy in fuel and enhancing the con venience and utility of vapor-stoves.

In the accompanying drawings, Figure 1 is a perspective view of a vapor-burner embodying my improvements. Fig. 2 is a vertical sectional view of the same. Fig. 3 is a hori- Fig. 2. Fig. 4 is a detail view.

A represents a cylindrical cup, which is made of metal and is provided in its upper edge with an annular groove,-B.

0 represents. an annular chamber, which is formed on-the outer side of the cup and is integral therewith. The said chamber, which constitutes the generating-chamber, is provided on one side with an inlet-opening, D, and on the opposite side with an outlet, E, and has tubes F extending horizontally therefrom in opposite directions."

G represents an annular channel which is formed in the vapor-generator and communicates with the opening E, and the other side of the annular channel communicates with the inlet opening D. v

H represents apair of curved channels,which are formed in the vapor-generator on the outer side. of thechannel G. The said channels H communicate at one end'with the tubes F, and the other. ends of the said channels communi-- cate with the inlet-opening D. The cup A ,SerlalNo.2=l1,649. (Nomodcll) constitutes a comminglingchamber. and is provided on the sideopposite the inlet-opening D with an induction-tube, I, which ex? tends horizontally fromits lower side.

K represents a drip-cup, which isarranged onthe lower side of the cup A.

V L represents a short'lvertical tube, which is 1 of considerable diameter, has its upper end open and its lower end closed, and passes up through the/cup A and drip-cup K. The outer side of this tube Lis provided with screw-threads at a suit-able distance fromits r lowerend.

' M represents a clamping-nut which screws on the tube L and bears against the under side of thedrip-cnp, and serves'to' support the said drip-cup and hold it close against ,the'cup A v or commingling-ohaniber, as shown, the dripcupK forming the bottom of the cupjA. Nrepresents a cold-water pipe, which; comable reservoir or other sourceot vwater, (not 7b 1 municates with the lower end of the pipe L is adapted to convey water thereto froma suitsho'wn,) and is provided with a 'stop-oo 'ck,O,-

by means of which the supply of water to the pipe L may be regulated; i

P represents a pipe,which is of considerably less diameter than the pipe-L and extends upward through the same, and is fitted snugly in an opening in the bottom thereof. This pipe P is designed to be connectedtoa suitable re-.-

ceiver for. hot watenwhich is also notshown',

.. as it forms no part of my present improve: ment. 1

R represents a has a threaded opening in its lower side adapted to engage the upper end of the pipe houow circular cap, which L. On the lower side of the cap R, at a suitable distance from the edge, is formed anam nular groove, S, the diameter of which is equal to the diameter of' the groove 13. "The upper end of the hot-water pipe E extends aslight .distanceabove the upper end of the.

cold-water pipeL, as shown in Fig. 2. From one side of the cap R extends a steam-pipe, T,

whiehrmay be connected to anydesired receptacle for steam,- and is provided with a stopcock, U. The space between the upper. edge of the commingling cup or chamber A and the 7 lower side ofthe cap R is closed-by a series of too segmental burner-plates, V, which are made of steel and have their upper 'and lower edges secured respectively in the grooves S and B. Each of the said burner-plates V is provided on one side with a narrow vertical opening, W, so that spaces are left between the opposing edges of the burner-plates.

From the foregoing description it will be readily understood that the cap B may be screwed from the upper end of the pipe L, so as to uncover the commingling-chamber and permit the burner-plates to be removed and cleaned or replaced by new ones. This removable cap R also enables access to be readily gained to the interior of the burner, so that the same may be cleaned when necessary in very short time and with little trouble.

The tubes F, which project from opposite sides of the vapor-generator, are provided with horizontal openings, which are arranged at right angles to and intersect their bores, and in the said openings are located needlevalves of the usual construction, which are provided with stufling-boxes, such as are commonly employed.

X represents a pipe which extends from the opening E, and is bent downward and communicates with a valve case or socket, Y, which is arranged opposite the outer end of the induction-tube I. In this sleeve or socket is located a third needle'valve, as shown. On

one side of the vapor-generator is secured a horizontal sleeve, Z, one end of which is opposed to one of the needle-valves in the tubes F.

A represents the curved elbow-pipe, which has one end fitted in the sleeve Z, and is adapted to turn therein, so as to direct the vapor from the burner in any desired direction. Thelatter is provided with a projecting handle-rod, B, whereby it may be turned and thus caused to direct the vapor into either of the series of pipes.

The operation of my invention is as follows: Initial heat is obtained inthe ordinary manner by igniting a small quantity of oil in the dripcup, thus causing the burner to become heated. Oil is then supplied to the generating-chamber through the usual Standpipe, D, which leads from a suitable reservoir and communicates with the inlet-opening D. A portion of this oil passes through the channel G and becomes vaporized therein, and is injected by the valve Y into and through the inductionpipe I. A suitable quantity of air is drawn into the commingling-chamber with the vapor, and is then mixed with the same to render the vapor combustible, when it ignites as it passes through the openings W between the burnerplates, thereby supplying heat suflicient for cooking purposes and at the same time heats the cap R to a very intense degree. The remainder of the oil finds its way through and becomes vaporized in the channels H, and is discharged by the needle-valves in the tubes F, to form auxiliary flames or jets. By thus providing the gas-generator with a series of channels, each of which leads to one of the burners, the latter are kept constantly supplied with vapor. Heretofore, as far as I am aware, vapor-burners have been provided with only a single channel to supply oil to the flames, and it frequently happensthat a single channel cannot feed vapor to the flames in proper quantities, and consequently the flames go out and permit the escape of vapor and render the burner dangerous.

In order to obtain a supply of hot water, the stop-cock N is opened and cold water is admitted to the pipe L and rises therein to the cap R, where it becomes thoroughly heated instantaneousl y. If the stop-cock in the steampipe is closed, the heated water will descend from the cap B through the hot-water pipe P to the suitable reservoir or receptacle therefor.

If it is desired to obtain steam, the stopcock in the steam-pipe is opened, and as the cold water reaches the cap B it becomes instantly converted into steam, and the-steam escapes through the pipe P, as will be readily understood.

Having thus described my invention, I claim-- I 1. The combination of the vapor-burner, the chamber or cap R, arranged above the same, the supply-pipe L, communicating with the cap or chamber R and extending through the burner, and the hot-water eduction-pipe P, extending through the pipe L into the cap or chamber R, substantially as described.
